Proton radioactivity is an important decay mode for nuclei near the proton drip-line. Studies of this decay mode can reveal valuable information on exotic nuclear structure and provide important information on the stucture of nuclei in extreme conditions. The new experimental data can let us understand the interactions in exotic systems, which motivate further theoretical development. The most recent application of the projected shell model(PSM) for proton emitters is represented. We study the rotational bands of the deformed proton emitter141 Ho by using the PSM. The experimental data are well reproduced. Strongly suppressed γ transition from the low-lying I~π= 3/2+state makes this state isomeric. Variations in the dynamical moment of inertia are discussed due to band crossings using the band diagram. The calculated results for proton emitter ~(151)Lu shows it is oblately deformed.
