It has long been speculated that magnetars are the engine powering repeating bursts from FRB sources4-13, but no convincing evidence has been collected so far14. Recently, the Galactic magnetar SRG 1935+2154 entered an active phase by emitting intense soft íray bursts15. One FRB-like event with two peaks (FRB 200428) and a luminosity slightly lower than the faintest extragalactic FRBs was detected from the source, in association with a soft íray/hard-X-ray flare18-21. Here we report an eight-hour targeted radio observational campaign comprising four sessions and assisted by multi-wavelength (optical and hard-X-ray) data. During the third session, 29 soft-íray repeater (SGR) bursts were detected in íray energies. Throughout the observing period, we detected no single dispersed pulsed emission coincident with the arrivals of SGR bursts, but unfortunately we were not observing when the FRB was detected. The non-detection places a fluence upper limit that is eight orders of magnitude lower than the fluence of FRB 200428. Our results suggest that FRB-SGR burst associations are rare. FRBs may be highly relativistic and geometrically beamed, or FRB-like events associated with SGR bursts may have narrow spectra and characteristic frequencies outside the observed band. It is also possible that the physical conditions required to achieve coherent radiation in SGR bursts are difficult to satisfy, and that only under extreme conditions could an FRB be associated with an SGR burst.   Description of the superdeformed bands of the odd-odd nuclei in Alpha similar to 150 region 期刊论文  OAI收割 COMMUNICATIONS IN THEORETICAL PHYSICS, 2002, 卷号: 38, 期号: 2, 页码: 200-204 作者:  Zhang, DL;  Liu, YX;  Liu, YX , Peking Univ, Dept Phys, Beijing 100871, Peoples R China.   |  收藏  |  浏览/下载：21/0  |  提交时间：2012/08/29 Interacting Boson Model  Identical Bands  Mass Region  Delta-i=4 Bifurcation  Extreme Conditions  Rotational Bands  Mean-field  Symmetry  States  Physics   Description of the superdeformed bands of the lutetium isotopes 期刊论文  OAI收割 COMMUNICATIONS IN THEORETICAL PHYSICS, 2000, 卷号: 33, 期号: 3, 页码: 503-506 作者:  Wang, JJ;  Zhang, YJ;  Wang, JJ , Peking Univ, Dept Phys, Beijing 100871, Peoples R China.   |  收藏  |  浏览/下载：14/0  |  提交时间：2012/08/29 Interacting Boson Model  u(16) Algebraic Lattice  Identical Bands  Delta-i=4 Bifurcation  Extreme Conditions  Spin Dependence  Triaxial Band  Nuclei  Symmetry  States   Systematic description of the superdeformed bands of the odd-A nuclei in the A=150 region 期刊论文  OAI收割 PHYSICAL REVIEW C, 1999, 卷号: 59, 期号: 5, 页码: 2511-2519 作者:  Liu, YX;  Sun, D;  Zhao, EG;  Liu, YX , Peking Univ, Dept Phys, Beijing 100871, Peoples R China.   |  收藏  |  浏览/下载：15/0  |  提交时间：2012/08/29 Interacting Boson Model  Identical Bands  Extreme Conditions  Mass Region  Mean-field  Symmetry  Bifurcation  Inertia  States  Moment
