Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A general solution of the model for positrons which diffuse inside a grain and then can be trapped and detrapped at a grain boundary of arbitrary shape is presented. The closed-form relations for the mean positron lifetime and the positron lifetime spectrum are obtained for a grain of spherical shape. The obtained results slightly differ from those presented in 1996 Phil. Mag. 73 1489 where a similar problem was considered and they extend the consideration given in that paper in J. Phys.: Condens. Matter 10 L547.
