Abstract：
Total Routhian Surface (TRS) calculations have been performed for even-even nuclei along proton drip line to study nuclear ground-state deformations, as well as the odd proton nuclei Ho and Tm isotopes. The drip line nuclei show the expected shape transition with the shell effects. Ground-state shape changes from prolate to oblate at ¹⁴³Ho and ¹⁴⁵Tm in these two isotopes, which is due to the γ instability around N=76.
