Lifetimes of excited states with spin I^\pi=23/2^--39/2^- belonging to the \pi h_11/2 band in ¹³¹La have been measured using the DSA method. The ¹³¹La nuclei were produced in the ¹²²Sn(¹⁴N,5n)¹³¹La reaction at E(¹⁴N)=70 MeV. Experimental data for the h_11/2 band in ¹³¹La have been compared with the CQPC and TRS model calculations. The additional experiment has been done to determine the stopping power parameters.
