An improved thermometer for intermediate-mass fragments
《Nuclear Science and Techniques》2016年第6期13-16,共4页Tian-Tian Ding Chun-Wang Ma 
An improved thermometer(TIB) is proposed for intermediate-mass fragments via the difference between isobaric yield ratios.The residual free energy of three isobars is replaced by that of the binding energy.The measure...
