The transitional nuclei in mass 80 region show a single particle and collective structure. It is dominated in low and medium spin by single particle nature and become more collective at high spin states for Z=37-40, N=45 nuclei, such as 81Kr and 87Mo.Recently in-beam y-ray spectroscopy study of transitional nuclei, such as 83Rb and 83Y, reveales a decay sequences built on high k state with enhanced ΔI=1 Ml transitions. It is interpreted in teams of a novel type of excitation, called “ magnetic rotation”. Our purpose is to study levels up to higher spin and to search for the magnetic band in 85Zr.High spin states of 85Zr were populated using 60N (28Si, 2pn)85Zr reaction with the beam energy The transitional nuclei in mass 80 region show a single particle and collective structure.

换上攀岩鞋,系好安全带,抓紧手窝踩实脚窝,身体后仰攀上与地面呈60度夹角的岩壁,一脚踏空,就有可能飞身跌落,从头再来。  36岁的望凯,对这种落差感可谓再熟悉不过。十年前,他和同样“人傻胆大”的合伙人开了一家室内攀岩馆,门票十元一张,月入2万元;创业中期,攀岩馆却因一次搬迁连亏四年;垂死转型,不再守门卖票的望凯绝处逢生,终于在创业第十个年头迎来黄金期。  望凯的创业轨迹,正应了攀岩运动的真谛——恒
