This paper reports measurements of two-pion femtoscopic correlations in Be+Be collisions at a beam momentum of 150 $$A\,\hbox {GeV}\!/\!c$$ (energy available in the center-of-mass system for nucleon pair $$\sqrt{s_{\text {NN}}} = 16.84$$ GeV) by the NA61/SHINE experiment at the CERN SPS accelerator. The obtained momentum space correlation functions can be well described by a Lévy distributed source model. The transverse mass dependence of the Lévy source parameters is presented, and their possible theoretical interpretations are discussed. The results show that the Lévy exponent $$\alpha $$ is approximately constant as a function of $$m_{\text {T}}$$ , and far from both the Gaussian case of $$\alpha = 2$$ or the conjectured value at the critical endpoint, $$\alpha = 0.5$$ . The radius scale parameter R shows a slight decrease in $$m_{\text {T}}$$ , which can be explained as a signature of transverse flow. Finally, an approximately constant trend of the intercept parameter $$\lambda $$ as a function of $$m_{\text {T}}$$ was observed, similar to previous NA44 S + Pb results (obtained with a Gaussian approximation, but unlike RHIC results).

The obtained momentum space correlation functions can be well described by a L\u00e9vy distributed source model. The transverse mass dependence of the L\u00e9vy source parameters is presented, and their possible theoretical interpretations are discussed. The results show that the L\u00e9vy exponent $$\\alpha $$ <math> <mi>\u03b1</mi> </math> is approximately constant as a function of $$m_{\\text {T}}$$ <math> <msub> <mi>m</mi> <mtext>T</mtext> </msub> </math> , and far from both the Gaussian case of $$\\alpha = 2$$ <math> <mrow> <mi>\u03b1</mi> <mo>=</mo> <mn>2</mn> </mrow> </math> or the conjectured value at the critical endpoint, $$\\alpha = 0.5$$ <math> <mrow> <mi>\u03b1</mi> <mo>=</mo> <mn>0.5</mn> </mrow> </math> . The radius scale parameter R shows a slight decrease in $$m_{\\text {T}}$$ <math> <msub> <mi>m</mi> <mtext>T</mtext> </msub> </math> , which can be explained as a signature of transverse flow. Finally, an approximately constant trend of the intercept parameter $$\\lambda $$ <math> <mi>\u03bb</mi> </math> as a function of $$m_{\\text {T}}$$ <math> <msub> <mi>m</mi> <mtext>T</mtext> </msub> </math> was observed, similar to previous NA44 S + Pb results (obtained with a Gaussian approximation, but unlike RHIC results)."
